APPLICATION

Air-Farm (Model: TT-200) can measure the Air Status such as: CO2, Temperature and Humidity values.
This model has three sensitive sensors, which makes it an optimum choice for installation in Factories or Greenhouses.

This interface supports RS485 communication and two analog output types (i.e, Voltage and Current).
So, this model can be connected to other systems. Maximum 100 devices are possible to be connected on RS485 bus, Each of these device can have 0-5V, 4-20mA Output.

This model has Active Low Output (NPN driven Output) for the systems such as Relays, LEDs, etc, for CO2 quality warning.
